This answer is unsupported. In the stimulus, we are comparing egg weight and volume to the weight and volume of an adult bird. This answer is comparing egg weight and volume of one species compared to the egg weight and volume of another.

This answer is unsupported. From the stimulus, we only know that the ratio between the weight and volume of an egg increases the smaller the adult bird is. This doesn’t mean that the eggs are larger, just that they account for a bigger proportion of an adult’s weight.

This answer is strongly supported. This answer accurately captures the comparative difference of proportion between egg weight and volume of different bird species.

This answer is unsupported. We don’t know from the stimulus anything about the size of any adult bird’s eggs. Rather, we only know something about the proportion of egg weight and volume compared to an adult bird.

This answer is unsupported. We don’t know from the stimulus whether bird species vary in egg size at all. We only know that in different species of birds, egg weight and volume accounts for a different proportion of an adult bird’s weight.
